Liquefication:occurs when an earthquake wiolent shaking suddenly turns loose, soft soil into liquid mud Aftershock:an earthquake that occcurs after a larger earthquake that happened in the same area Tsunami:water that is shaken violently enough to form large waves and the hieght increases as it reaches the shore Base-Isolated Building:a building that is designed to lower the power of an earthquake as it reaches the building
Outline
How Earthquakes Cause Damage
Local Soil Conditions
Loose soil shakes more harder than solid rock
The thicker the soil is, the more shaking there will be
A house built on rock will shake less than a house on sandy soil
Liquefaction
Liquefaction turns loose,soft soil into liquid mud, and can trigger mudslides and landslides
Liquefaction likely occurs where soil is full of moisture/water
Aftershocks
Building's that have been weaken by an earthquake can fall during an aftershock
Aftershocks can happen hours, weeks, or months after an earthquake has happened
Tsunamis
When an earthquake shakes the sea floor, a tsunami is made
A tsunami gets bigger as it reaches the shores of land
A tsunami's waves can be as big as from 100 kilometers to 200 kilometers
